Efest LUC Charger V4

It's just another 4-bay charger, right? Wrong! The V4 will charge 4 cells at either 0.5A or 1A. But that's not all! You can also charge 2 cells at 2A each, which is super fast! In addition, you can fit two 26650 batteries, and at 2A, you won't have to wait all day for a full charge. This charger is compatible with most battery sizes, including 16340, 18350, 10440, 18490, 14500, 18500, 16650, 18650, and 26650 batteries. After it's plugged in, just press the button next to the screen to change your charging speed. The screen will display each battery's voltage in real-time to one decimal point. Each channel is independent, so your batteries charge quickly regardless of how many are on the charger at one time. The LUC v4 may also be able to resurrect over-discharged cells. Lastly, the LUC v4 can act as a power bank if you're in a pinch. Simply unplug the charger from the outlet with batteries in the channels, plug in your device via the USB port in the back, and hold down the button. An icon will indicate that it's charging your device. This charger comes with an AC cable and a car charging cable for use in your cigarette lighter port. This is the perfect charger for people that use 26650 batteries, have multiple mods/batteries, or like to be fully-stocked with charged batteries at all times!

Note: In general, smaller batteries should use slower settings. Refer to your battery's documentation to find your battery's maximum charging current.
